OperationThe speed switch is designed for use in applicationswhere manually setting the capacity (speed) is desir-able. Switching is carried out between three presetspeeds: low – medium – high, as well as switched out.An LVDZ-17-3 valve, LVDZ -18-3 or LVDZ -19-3 roomthermostat and LVDZ-22-3 timer can be wired to theswitch. Simple and cost-effective control equipment for
the unit heater can be obtained using the switch andone or several accessories shown above. Several unit heaters can be wired to one and the samespeed selector, however the total capacity must notexceed 2 Aand 9Arespectively.

Installation Example
OperationThe automatic unit heater control, ATC, advanced, LVDZ-29,regulates the speed of the unit heater motor in three presetsteps in response to ambient temperature readings from thetemperature sensor supplied. The desired temperature (setpoint) is set with the potentiometer set in the Automatic unitheater control mode. If the ambient temperature is warmerthan the preset temperature, the control system reduces thespeed step by step and when no heating is needed, it shuts offthe fan motor. If the ambient temperature is lower than thepreset temperature, the controller increases the speed step bystep and the capacity as well. ATimer (LVDZ-22-3) can be wired to the ATC for loweringthe air temperature at night. Desired “night temperature” canthen be set by means of another potentiometer in theAutomatic temperature control system.Automatic temperature control system can also be controlledin response to a 0-10 V signal. Remote control is available as anaccessory (LVDZ-21-3).
Aseparate water valve with thermal actuator (LVDZ-17-3)can be connected to the Automatic temperature controlsystem. When the desired air temperature has been reachedand the fan has stopped, the valve closes and shuts off waterflow. When the air temperature drops and the fan starts, the valve
opens again. In the event of a power failure, the valve willopen.CAUTION! External solenoid valves must not be connectedto the Automatic temperature control system because a surgeof current is likely to occur when they are switched on.The Automatic temperature control system is tested to estab-lish its electromagnetic compatibility (EMC) in accordancewith SS-EN 50081-1 and EMC-immunity in accordance withSS-EN 50082-2.For particulars of alternative speeds, see page 32.

Speed control, advanced
The control system can be supplemented with remotecontrol across a cable (LVDZ-21-4 or a remote infraredunit LVDZ-36). Then the fan can control the speed inthe automatic mode or three fixed speeds 1,2,3 or stopthe fan in 0 position.The control system has provision for control by meansof a 0-10 V signal from a microprocessor substation, ora LAN network control.An external fault alarm signal input can be wired to thecontrol system.For particulars of alternative speeds, see page 32.
Installation Example
Operation:When heating is needed, the liquid valve (LVDZ-17-4)opens and the automatic fan control system, inresponse to signals from the temperature sensor,controls the fan to accelerate or decelerate in three fixedsteps to maintain the preset temperature. When heat-ing is no longer necessary, the liquid valve closes andthe fan stops.The temperature can be preset by means of buttons onthe cover. If the ventilation system is equipped with atimer for an optional temperature, that temperaturecan also be preset.

Example 1. Workshop Halls, Warehouses1. Start by measuring the floor surface of the premises.
Assume a warehouse with a floor surface of 10 m x 24 m = 240 m2.
2. Then estimate the ceiling height.For our example, we estimate a ceiling height of 4 m,which means that we can use the chart on the next page.
3. Then estimate the nature of the building and the typeof heating used. The warehouse is relatively new with good insulation,but totally lacks basic heating. Select 80 W/m2 from thechart below.
4. Estimate the capacity required.In this case, the capacity required will be 240 x 80 =19.2 kW. Select the number of unit heaters needed.As a rule of thumb, each unit heater can heat 100 m2
(10 m x 10 m). In this case, 3 units are therefore needed. We then will have 6.4 kW per unit heater.
5. Then plot the appropriate water temperature andinlet air temperature in the relevant table for heatingon pages 26 and 28. We intend to use 55–35 °C water, and maintain about 20 °C in the premises. We select three LVDV-40-1 units, which, at the given values, will each provide 6.5 kW operating at 900 r/minand meet our requirements. Atotal capacity of 19.5 kW.
6. Motor.We select a single-phase, 230 V motor for simple instal-lation. Should boosted capacity be required, the motorcan easily be re-switched to a higher speed.
7. Select accessories required.We included three LVDZ-04-40 discharge air devices to ensure that the discharged warm air will reach the lower occupied zone. We also select one LVDZ-18-3 room thermostat per air heater for maintaining uniform temperature in the premises.Our purchase list will then be: Three LVDV-40-1Three LVDZ-04-40Three LVDZ-18-3
Example 2. Shop Entrances, Doorways1. Start by measuring the volume of the entrance.
Assume an entrance with a floor surface of 3 m x 4 m and a 3 m high ceiling.The volume will then be 3 m x 4 m x 3 m = 36 m3.
2. Then use the key figure 200 W/m3 to calculate the capacity requiredThe capacity required will then be 36 x 200 = 7.2 kW.
3. Then plot the appropriate water temperature in thetable on page 28, and read the capacity at an inlet airtemperature of 20 °C, which is advisable.In this case, we will use 70–40 °C water.
4. The size of unit and the fan motor speed can be obtained from the table.To keep the sound level low, 700 or 900 r/min is advisable.We select a size 40 unit with the fan motor operating at 670 r/min which provides 7.9 kW.
5. Motor.We select a single-phase, 230 V motor for simple instal-lation. Should boosted capacity be required, the motorcan easily be re-switched to a higher speed.
6. Select the accessories required.We intend to mount the air unit in the ceiling and there-fore need a suspension rod set. Our purchase list will then be:One LVDV-40-1One LVDZ-03

Technical Data
The accessories LVDZ-15-4, LVDZ-24-3, LVDZ-25-3,LVDZ-28, LVDZ-29 and LVDZ-33 include a transformerwhich, besides 230 V output current, has five lower volt-ages for lower speed. The LVDZ-15-4, LVDZ-29 andLVDZ-33 operate with 3 different voltages. These acces-sories are factory-wired making it possible to obtain theappropriate speed for each step.The table above shows the factory-wired voltages andcorresponding speed. If for some reason it is desirable toalter the speeds, this can be done by reconnecting theflexible connections on the transformer.
Detailed wiring diagrams for motors and accessoriesare provided in the installation, operation and mainte-nance instructions for the LVDV.
